【摘要】 本文用试验法测量出引信后座机构所受的冲击加速度信号ａ（ｔ）以及惯性块的后座位移ｓ（ｔ），并用优化的算法求解出机构的等效阻尼系数Ｃ，文章着重介绍了测试系统的３个主要子系统：激励系统；加速度、位移信号传感系统以及数据采集、记录和分析系统。同时介绍了位移传感器的设计和制作。更多还原

【Abstract】 in this paper, the acceleration a (t) acting on the initia mechanism and thedisplacement s(t) of the mechanism were measured, and then, using the optimization algorithm,the equivalent damping coefficient was obtained. The peper discussed the choice of measurementinstruments and some major subeytems of the measurement system which included excitjingsystem;sense devices for acceleration and displacement as well as data acqusition, recording andanalysis system. The design and mating of displacement sensor were also discussed.更多还原
